使用64位的android 32位JNI库
我已经尝试使用本机库上的Nexus 9上运行的应用程序。
I've tried running an application using a native library on the Nexus 9.
有一个错误信息的应用程序退出：
The application exits with an error message:
java.lang.UnsatisfiedLinkError: dlopen failed: "lib_xyz.so" is 32-bit instead of 64-bit
是否有任何已知的解决这一问题（除，当然，重新编译库和决策的APK更大）？
Is there any known workaround for this problem (except, of course, recompiling the library and making the apk bigger)?
找到一个解释：64位的Android可以使用32位本机库作为备用，只有当System.loadlLibrary（）找不到什么更好的默认的搜索路径。 你得到的UnsatisfiedLinkError如果强制系统加载使用System.load（）与全库路径的32位库。 因此，第一个解决方法是使用的System.loadLibrary（）而不是System.load（）。
Found an explanation: 64-bit Android can use 32-bit native libraries as a fallback, only if System.loadlLibrary() can't find anything better in the default search path. You get an UnsatisfiedLinkError if you force the system to load the 32-bit library using System.load() with the full library path. So the first workaround is using System.loadLibrary() instead of System.load().
这是必须要考虑的另外一个事情是，库不能混用：回退行为仅适用于第一个库应用程序的负载。如果第一个是64位的，没有32位的库可以通过相同的应用程序，反之亦然加载。
An additional thing that has to be taken into account is that libraries cannot be mixed: the fallback behaviour only applies for the first library your application loads. If the first one is 64-bit, no 32-bit libraries can be loaded by the same application, and vice versa.
